Im really hurt. Is it ok to be hurt?

Well, it's Easter and I just got to my grandpa's where my dad and 2 younger siblings stay the weekend when it's my dad's turn to have them. They are 8 & 14. I know Easter is for kids, but I got my dad some candy and his favorite pop so he wasn't left out. Well, I found out that they did all the Easter stuff yesterday. Dyed eggs, hid and found the eggs, opened their gifts. All without me.... And now my dad didn't even get me a single piece if candy or anything. I know the holiday really is for kids, but I'm still one if his kids and I got him a gift and I get nothing..... I'm just really hurt and upset. Is it ok to be or am I being a baby?? 😞💔
